[R] loop problem

[crenial30]

I have the following code which I wanted to convert using for loop

previous code:
R_ev1 <- R_event[R_event > (rx[1] + 300*0)& R_event <= (rx[1] + 300*1)]
R_ev2 <- R_event[R_event > (rx[1] + 300*1)& R_event <= (rx[1] + 300*2)]
R_ev3 <- R_event[R_event > (rx[1] + 300*2)& R_event <= (rx[1] + 300*3)]
R_ev4 <- R_event[R_event > (rx[1] + 300*3)& R_event <= (rx[1] + 300*4)]

R_ev5 <- R_event[R_event > (rx[1] + 300*4)& R_event <= (rx[1] + 300*5)]
R_ev6 <- R_event[R_event > (rx[1] + 300*5)& R_event <= (rx[1] + 300*6)]
R_ev7 <- R_event[R_event > (rx[1] + 300*6)& R_event <= (rx[1] + 300*7)]
R_ev8 <- R_event[R_event > (rx[1] + 300*7)& R_event <= (rx[1] + 300*8)]

R_ev9 <- R_event[R_event  > (rx[1] + 300*8)& R_event <= (rx[1] + 300*9)]
R_ev10 <- R_event[R_event > (rx[1] + 300*9)& R_event <= (rx[1] + 300*10)]
R_ev11 <- R_event[R_event > (rx[1] + 300*10)& R_event <= (rx[1] + 300*11)]
R_ev12 <- R_event[R_event > (rx[1] + 300*11)& R_event <= (rx[1] + 300*12)]

R_ev13 <- R_event[R_event > (rx[1] + 300*12)& R_event <= (rx[1] + 300*13)]
R_ev14 <- R_event[R_event > (rx[1] + 300*13)& R_event <= (rx[1] + 300*14)]
R_ev15 <- R_event[R_event > (rx[1] + 300*14)& R_event <= (rx[1] + 300*15)]
R_ev16 <- R_event[R_event > (rx[1] + 300*15)& R_event <= (rx[1] + 300*16)]


R_ev1c <- as.character(R_ev1)
R_ev2c <- as.character(R_ev2)
R_ev3c <- as.character(R_ev3)
R_ev4c <- as.character(R_ev4)
R_ev5c <- as.character(R_ev5)
R_ev6c <- as.character(R_ev6)
R_ev7c <- as.character(R_ev7)
R_ev8c <- as.character(R_ev8)

R_ev9c  <- as.character(R_ev9)
R_ev10c <- as.character(R_ev10)
R_ev11c <- as.character(R_ev11)
R_ev12c <- as.character(R_ev12)
R_ev13c <- as.character(R_ev13)
R_ev14c <- as.character(R_ev14)
R_ev15c <- as.character(R_ev15)
R_ev16c <- as.character(R_ev16)




lis1 <- c(
length(R_ev1c),
length(R_ev2c),
length(R_ev3c),
length(R_ev4c),
length(R_ev5c),
length(R_ev6c),
length(R_ev7c),
length(R_ev8c),
length(R_ev9c),
length(R_ev10c),
length(R_ev11c),
length(R_ev12c),
length(R_ev13c),
length(R_ev14c),
length(R_ev15c),
length(R_ev16c)
)


# R_ev1_mat <- matrix(unlist(R_ev1),nrow=T)


barplot(lis1, angle = 15+10*1:5, density = 20, col = "black",
       legend = rownames(lis1))
 title(main = list("Number of Occurred Received events in every 5 mins",
font = 4))

# dev.off()


New code:

f1<- seq(rx[1],rx[2],by=300)
f<- as.character(f1)
len <- length(f)

for (n1 in 0:(len-1)){
for(n2 in 1:len){
# R_ev_01 <- R_event[R_event <= (rx[1] + 300)]

R_ev[n1] <- R_event[R_event > (rx[1]+ n1*300)& R_event <= (rx[1] + 300*n2)]
R_ev_char <- as.character(R_ev)

lis01 <- list(length(R_ev_char))
barplot(lis01, angle = 15+10*1:5, density = 20, col = "blue",
       legend = rownames(lis01))
 title(main = list("Number of Occurred Received Events in every 5 mins",
font = 4))
}
}

Somehow it is not working and giving an error saying "Fehler in -0.01 *
height : nicht-numerisches Argument für binären Operator".

Any help would be really appreciated.

Thanks
Crenial
